Hypercholesterolemia, familial, 1 Uncertain:1
This missense variant (also known as p.Asn309His in the mature protein) replaces asparagine with histidine at codon 330 of the LDLR protein. Computational prediction tools and conservation analyses are inconclusive regarding the impact of this variant on the protein function. Computational splicing tools suggest that this variant may not impact RNA splicing. In a high-throughput LDL uptake assay, this variant has been determined to be non-disruptive to LDLR function (PMID: 25647241). To our knowledge, this variant has not been reported in individuals affected with familial hypercholesterolemia in the literature. This variant has been identified in 6/282428 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
Familial hypercholesterolemia Uncertain:1
This missense variant replaces asparagine with histidine at codon 330 of the LDLR protein. This variant is also known as p.Asn309His in the mature protein. Computational prediction suggests that this variant may not impact protein structure and function. In a high-throughput LDL uptake assay, this variant has been determined to be non-disruptive to LDLR function (PMID: 25647241). To our knowledge, this variant has not been reported in individuals affected with LDLR-related disorders in the literature. This variant has been identified in 6/282428 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
